WINDING-MACHINE.

and useful Improvements in Winding-Ma-' chines, of which the followingis a full, clear,v

and exact description, such as will enable others skilled in the art towhich it appertains to make and use'the same. This invention relates tomachines for coiling or winding continuous strips of material andespecially to machines for winding or ceiling a continuous web of paper,cardboard or similar material. 1

One object of the invention is .to produce a machine for eflici'entlywinding a web into a compact bundle or roll;

Another object of the'lnvent'ionis the production of a practicalmechanism to wind OIfCOil a'web in accordance with the rate of deliveryof the web to the mechanism. p Another. object ofthe invention is theproduction of a simple device to guide the web asjit is coiledsoastoproduce a coil in which the edges of the convolutions aline with. eachother avoiding projecting portions.

Another object :oftheinvention is the efiicient. production of atightly-coiled roll.

Another object of the invention is to pro- 1 duce a mechanism of thecharacter described which may be readily manipulatedand'controlled. r

Still another object of the invention is to produce anefiicaciousmachine capable of rewindin' the web into its original form.

Still'ot er objects will be in part obvious or support having a smoothupper surface.

and in part pointed out hereinafter. The invention accordingly consistsin the features of, construction, combinations of elements andarrangements of parts which will be exemplified 1n the constructionhereinafter set forth, and the sco 'e of the application of which willbe in icated in the 7 following claims.

larged; Fig- 4 is a side view of the guiding and tension device showninFig. 3; Fig. 5 1s a transverse section through the tension' plateshowing the shape of the guide bars and the manner-of securing them inposition on the tension plate; and Fig. 6 1s a vi ew of the controllerroller and its sustaining connections. 7 Although the present embodimentof the unvent-ion is adapted to wind or c'oil'a web delivered from anysuitablesource it isespecially useful in connection with a slow andvariable delivery such as when a web is delivered from a machine whichproduces continuous scores thereinl At 1 is indicated diagrammatically amach1ne' for scoring a web. Said machine comprises feed rollers 22between which the web is gripped and fed past rotary scor- "ing'rollers3-3, these latter producing parallel continuousScores 4-4 1n the web. ItIS evident that the web may be fed 'to the scoring machine from any.suitable source of supply and in the resent embodiment it is preferredto provi ea roll of web 5 centrally supported upon a shaft journaled inbearings 6 on a suitable frame work 7. As iv the scoring machineocratesthe feed rollers 2 draw the web rom the supply roll {rand the web isdelivered from the scoring machine to the' winding or coiling mechanlsm.

The frame 7 may he of any suitable con-.

struction but is preferably composed of metallic bars arranged as shownand providing elevated supports for the parts ofthe folding, coiling orwinding mechanism as well as for the roll 5. o I

8 represents a preferably horizontal table A bracket 9 secured to theframe supports a comparatively large guide roller 10 near. one end ofthe table. The web after leaving the feed rollers 2 passes around guiderollers 12 and 13, over a controlling roller 14 hereinafter moreparticularly described,

thence around the guide roller 10 from which it passes over the smoothsurface of the table, thence to the winding mechanism hereinafterdescribed.

As will hereinafter appear the winding mechanism for the web comprisesin its preferred form a rotary'drum or roller u n which the web iscontinuously coiled, an in order that the coil shall be tight and the 20ries of parallel lugs or rds'20 is formed on es of the-roll free fro PZ-ojecti g per;

tions of the web, a device comprising 'a plate 15 is provided to guideand tension the web prior to its delivery to the winding roll. The.weight of'this plate is determined by the tension desired and it restsupon the web as it passes across the table 8, being removably retainedin position by pins or projections 16. extending hpwardly. from theframes 7, and engaging guiding openings in cars 17, projecting laterallyfrom the plate 15. Projecting from either end of the table 8 are arms 18supporting Web guiding rollers 19 a short distance from the respectiveends of the table. The tension device is so constructed and positionedas to serve to some eiztent as a guide for the web inasmuch as the pins16 will prevent any extreme lateral movement of the web, but in order toprovide an accurate guide forthe web, a seor secured to th e' bottom ofthe plate 15, the bottom edges of said lugs or rods being shaped orbeveled to engage the scores of the web as the latter passes over theplate 8, the ends of the bottom edges being curved to readily receivethe web. In order to secure the rods 20 to the plate, the latter istransversely slotted preferably near each end and screw threaded pins 21secured to each rod project upwardly through the slots and are engagedby nuts 22 whereby the rods 20 may be securely clamped to the bottom ofthe plate and adjusted so as to be transversely disposed correspondingto, the disposition of the scores in the web.

After being operated upon by the tension device the Web passes to thecoiling or winding mechanism. In the present embodiment the windingdevice comprises a horizontal shaft or roller 23 journaledin the frame7. The shaft or roller- 23 is adapted to be driven in such a manner asto take up the web as it is delivered from the machine which haspreviously operated thereon. The movement ofthe roller 23 is effected bya gripping mechanism, preferably frictional, which at a proper time isoperated to couple the shaft 23 with a motor or driving mechanism.Secured to the roller 23 is a belt pulley 24 adapted to be driven by afriction belt 25. The belt is continuously moved, or driven from asuitable source such as an overhead pulley 26 and under certainconditions passes loosely around the pulley 24 without suflicientfrictional contact with the latter to effect any movementthereof. 27represents a contact roller journaled in a movable frame pivotallymounted at 28 on a standard 29 projecting upwardly from the frame 7. Themovable frame for the roller 27 preferably comprises parallel connectedbars 30 and 31, at the outer ends of which the roller 27 is journaled,their opposite ends being pivotally connected to the standard 29 asexplained. Thebelt- 25 extends between the arms 30 and 31 and theconstruction is such that the roller 27 is adapted to lie or restagainst a ply of the belt 25 and regulate the pressure and the arc ofcontact between the beltand the pulley 24, this being permitted by themovable framepivoted as aforesaid. The tractive effect of the belt 25 onthe pulley 24 is thus governed by the position of the pulley 27, as itincreases the arc of contact between the belt and pulley in its innerposition or that toward the pulley, and decreases said are of contact inits outer position.

In order to control the contact between the driving belt and the pulleymeans are provided to move the roller 27 to vary the arc of contactabove referred to. Depending from a suitable point located preferablyabove the table 8 is a vertical frame comprising parallel pairs ofspaced guide rods 32 forming slots or guide ways in which the gudgeons33 of the roller 14 are adapted to freely move. up and down. Eye-pieces34 loosely surround each gudgeon and are connected by cords 35 and 36'passing over suitably supported guide rollers 37 and 38 to the movableframe carrying the roller, 27 preferably at the outer end of said frame.

up and down in'its guide ways the roller '27 is moved from and towardthe periphery of the pulley 24 changing the arc of contactbetween saidpulley and the belt 25. A spring 39 is connected at one end to themovable frame of the roller 27 and at the other end to a portion of theframe 7 to positively effect the inward movement of the roller andassist in setting the gripping mechanism 27. i

In operation the supply roller 5 is loosely journaled on: its support 6and the end of It will be observed that as the roller 14 moves the .webthreaded, in this instance, through the scoring machine between the feedrollers 2, thence around the guide rollers 12 and 13, thence over theroller 14 and around the guide roller 10, over one roller 19, and

between the plate 15 and the table 8 from which it passes over the otherroller 19 to the shaft or drum 23 on which it iS to be wound and towhich the end of the web is.

suitably secured; The main driving pulley 26 being new set in motion,and the scoring attached to; said pulley will also be rotated until thetractive force between the two is .insuflicient' to drive the pulleyagainst the driven, the Web being unwound therefrom to coil the webthereon. The coiling of the web on the drum will result in taking up theslack of the web and in drawing down the roller 14, which lattermovement results in a movement of the roller 27 away from i the pulley24, thus decreasing the tractive effect between said pulley 'and thebelt 25 resistance oifered by the tension of the web. Thus the rotationof the drum 23 and the folding or coiling of the web thereon is governedby the. rate of delivery of the web and continuous and automaticoperation of the severalv parts of the apparatus is permitted" todeliver and wind up the web. notwithstanding any variations which mayoccur in the delivery.

It will be observed that the flexible connect-ion" between thecontroller and the operating mechanism" permits the movements of saidparts and eliminates compression strain therebetween, whereby the riseof the controller is resisted practically'by only its own weight, thusdoing away with intermediate connections, the inertia of which mightinterfere with the accuracy of the control of the web.

In the present embodiment it will be noted that the delivered web isthreaded around several guide rollers and around the movable controllingroller 14 before it. engages the tension and guiding device. It isobvious, however, that the invent-ion is not limited to the particularconstruction described and that the'web may be extended directly fromthe delivery mechanism to the tension device if desired.

It may be desirable to rewind the web into the relative arrangement ithad on the supply roll, and the shafts of the spaced reels or rollers 5and 23 are provided with pulleys 40 and 41, respectively, adapted to beconnected by suitable driving belt. \Vhen the web has been wound on theroller 23, its trailing end may be secured to the roller 5, and saidroller rotated in the proper direction to rewind the web thereon in itsori 'nal relation thereto. When so operate the controlling roller ismaintained in its upper posit-ion by the weight of the roller 27 and itssupporting frame, assisted by the s ring 39. Thus the belt 25 is heldagainst t e pulley 24, and the roller 23 continuously and wound on theroller 5 in a manner which will be apparent from the foregoing exlanation.

Ihus by means of the above described apparatus the several objects ofthe invention are accomplished in a practical and efiicient manner.

As many changes could be made in the above construction and manyapparently widely different embodiments of this invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted asillustrative and not in a limiting sense.

v It is also to be understood that'the language used in the followingclaims is intended to cover all of the generic and specific features ofthe invention herein described and all statements of the scope of theinvention, which, as a matter of language, might be said to falltherebetween.
